Automatic Radius Measurement (ARM) system

With PBT's automatic radius measurement system (ARM), even complex forms with demanding materials can be manufactured without error, material waste with operators who may not have years of know-how. For many radii it is thus possible to achieve all nominal values without rejects and costly and time- and material-consuming test runs. In most cases even changed material properties can be handled without any problems.

Fully automatic radius measurement is based on PBT's PC400 control systems
The pneumatic gauge heads are positioned variably to the right and left of the bending rollers
Measurement of one or more different radii in the same profile is possible
Continuous and cyclical measurement of the actual manufactured radius possible
Springback is measured and corrected based on the outcome of the initial pass
After measurement of the actual manufactured radius, automatic correction takes place until the specified radius is reached

Mandrel bending device - 1500 CNC-controlled

With a PBT mandrel bending device option, operators can achieve clean bends with challenging materials without distortion.

Supporting roller controlled

(Z-axis) for right and/or left 3D bending
The controlled supporting roller additionally makes it possible to bend with a gradient. With the associated software, the supporting roller makes it simple to program and bend 3D elements.
